It stands for genetically modified organisms. It would be non heirloom. Companies like Monsanto that have bought up most of the worlds seed supplies and modified them to do things like produce their own pesticide, be immune to pesticides, and to not produce viable seed. That way farmers have to buy seeds yearly. This is the company that developed and sells Roundup weed killer. They have been producing poisons since the early 1900's and now they own most seed companies. It's really scary. It's worth looking up if you buy seeds ( or eat food). This is why I'm trying to start my own garden this year. Thanks! :)
then in that case you are safe with these seeds..... Sorry I did not know what is was but I will remember incase some one else should ask. Thank you for the interest...GOOG LUCK and Happy Bidding
